STMicroelectronics Breaks Down Barriers
to Broad Adoption of Vibration Monitoring in Industry 4.0
Applications
- IIS3DWB MEMS vibration sensor optimized for industrial
monitoring
- Plug-and-play evaluation kit accelerates application
development
- Convenient and economical solution for condition-based
maintenance
Geneva, March 30, 2020 – STMicroelectronics (NYSE:
STM), a global semiconductor leader serving customers
across the spectrum of electronics applications, is powering the
next generation of Industry 4.0 applications with a new
vibration-sensing solution optimized to enable smart maintenance of
factory equipment.
ST’s IIS3DWB vibration sensor and supporting STEVAL-STWINKT1
multi-sensor evaluation kit accelerate development of
condition-monitoring systems that boost productivity by inferring
equipment maintenance needs. Analyzing the sensed vibration data
locally or in the cloud helps owners create strategies that
maximize uptime, minimize servicing costs, and avoid emergency
repairs.
The IIS3DWB is a 3-axis MEMS1 accelerometer optimized for
industrial vibration sensing. The STEVAL-STWINKT1 simplifies
prototyping and testing by integrating the IIS3DWB with additional
sensors, an ultra-low-power microcontroller and algorithms for
vibration processing, Bluetooth® wireless module, and USB
connection. Housed in a plastic enclosure with a battery, the kit
is ready to begin application development and presents a convenient
reference design. High-speed data-logger and cloud-dashboard
utilities are included to help collect, analyze, and visualize the
results.
“Machine-condition monitoring is central to industrial digital
transformation, bringing the power to enhance manufacturing
performance and safety while enabling new services and business
models,” said Alessandro Cremonesi, Vice President of System
Research and Applications, STMicroelectronics. “Our vibration
sensor and IIoT multi-sensor development kit and reference design
are the best performing and most affordable solutions in the market
today, enabling high-performance and cost-effective plug-and-play
industrial sensing.”
ST is already supplying the IIS3DWB to IIoT technology innovator
SPM Instrument of Sweden, for use in the Company’s AIRIUS wireless,
battery-powered vibration sensor. Rikard Svärd, Global Sales
Director of SPM Instrument commented, “We chose IIS3DWB for its
unique combination of features, including 3-axis sensing, wide
bandwidth, and low noise in a low-power, digital device, which
helped us achieve the performance, design-cycle time and cost
targets we set for AIRIUS.”The IIS3DWB vibration-sensing
system-in-package is in production now and available for $9.00 in a
14-lead plastic land grid array (LGA) package. The STEVAL-STWINKT1
is available from ST for $99.00.
Further technical information ST’s
state-of-the-art IIS3DWB 3-axis ultra-wide-bandwidth MEMS
accelerometer detects vibrations that are prime indicators of a
machine’s service requirements. The device, which is covered under
ST’s 10-year availability assurance for industrial products, is
optimized for vibration monitoring. The frequency response is
tailored to be fully flat and with low noise up to 6kHz and then
with a sharp cutoff and high attenuation to remove
frequency-aliasing concerns and to detect machine-related faults
with accuracy and consistency. Low power consumption maximizes the
operating lifetime of independently powered sensor nodes. Key
features of the IIS3DWB include:
- Accelerometer with wide and flat frequency response over 3-axis
saves external signal conditioning and complexity needed by
competing sensors
- Digital plug-and-play capability, integrating signal
conditioning, analog-to-digital converter (ADC), filtering, and
bandwidth equalization on-chip
- Low noise: 75µg/√Hz in 3-axis mode or 60µg/√Hz in single-axis
mode selectable on the fly
- -40°C to 105°C operating-temperature range
- 1.1mA operating current at full performance in all three
axes
Leveraging ST’s leading position in MEMS technology, the
STEVAL-STWINKT1 evaluation kit integrates multiple miniature
sensors on-board in addition to the IIS3DWB. There is also a
Bluetooth® Low Energy (BLE) radio for connecting to an edge device
or directly to the Internet. The many on-board features let
solution integrators bypass labor-intensive sensor integration to
focus on their application and accelerate time to market and offer
advanced software features like high-speed data logging for the
benefits of new field of exploration like machine learning and AI.
The price of the kit is more than 75% less than some alternatives
in the market and eliminates a significant cost barrier to Industry
4.0 digital transformation.
Features of the STEVAL-STWINKT1 include:
- Best-in-class industrial sensors: inertial sensors,
temperature, pressure, and humidity sensors, and digital and
wide-bandwidth analog microphones
- Ultra-low-power Arm® Cortex®-M4 MCU (STM32L4R9ZI) running at
120MHz with FPU, 2048 kbytes Flash, and optimized power
management
- On-board footprint for STSAFE-100 secure element IC for secure
connection and authentication
- Wireless BLE4.2 on-board and wired RS485 and USB OTG
connectivity
- Preprocessing algorithms for vibration analysis: RMS moving
average and programmable FFT (overlapping, averaging,
windowing)
- High-speed data logging with real-time storage on SD-CARD and
streaming via USB of data from multiple (22) sensors at their
maximum resolution (ODR)
- Companion cloud application and dashboard
- Optional Wi-Fi expansion board (STEVAL-STWINWFV1), and STMod+
cellular expansion board from the P-L496G-CELL02 kit
